Physical Description
Cuvier's beaked whale has a short beak in comparison with other species in its family, with a slightly bulbous melon. The melon is white or creamy in color and a white strip runs back to the dorsal fin about two-thirds of the way along the back. The rest of the body color varies by individual: some are dark grey; others a reddish-brown. Individuals commonly have white scars and patches caused by cookiecutter sharks. The dorsal fin varies in shape from triangular to highly falcate. The fluke of the whale is about one-quarter the body length. The whale grows up to about 7 meters (23 ft) in length and weighs 2–3 tonnes (2.0–3.0 long tons; 2.2–3.3 short tons). They live for forty years.
The Cuvier's beaked whale is difficult to distinguish from many of the mesoplodont whales at sea.

“Life on board a pleasure steamer violates every moral and physical condition of healthy life except fresh air.... It is a guzzling, lounging, gambling, dog’s life. The only alternative to excitement is irritability.”
—George Bernard Shaw (1856–1950)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
